My invention relates broadly to hair wavmg apparatus and moreparticularly to a construction of casing for the'heater employed in hairwaving operations.

One of the obgects of my invention is to provide a constructionnofheater for use in air waving apparatus having a casing capable ofremaining at a relatively low temperature independently of therelatively high temperature to which the heating element within the hairwaving apparatus'maybe raised. A Another object of my invention is toprovide a practical construction of-casing for a heater employed in ahair waving apparatus where the parts of the casing may be moldedinexpensively on a quantity production basis and connected one withrespect to the other forprov'idin' a substantially shell-like. enclosurefor a eating element, protecting the patron and operator against burnsdue to hi h temperature; 7 till another object of my invention is toprovide a construction of casing for an electric heater for hair wavingin which 2. casing of shell-like construction is provided, withventilating means disposed in one portion of theshell-like casing, thecasing having means for interconnectingthe portions thereof to provide aheat-resisting enclosure.

A still further object of my invention resides in the construction of acasing for hair waving apparatus, wherein the heater memher is in theform of a cylindrical device, with means for preventing the leakage of'condensate from the casing, thereby preventing injury to a patronduring a hair waving operation. c

Other and further objects of my invention hair waving apparatus in whichthe casing is formed in two parts related one to the other for compactlyhousing a heater member, as more fully set forth in the specificationhereinafter following by reference to the accompanying drawings inwhich:

Referring to the drawings .indetail, reference character 1- designatesthe upper por-.

'In the upper end of the shell 1 there is pro vided an annular p0rtion'6which terminates in a head portion 7 withan aperture 8 therein. Thiscone shaped undersurface acts as a guide for rod 24 making insertion ofrod 24 in aperture 8 quick and positive. The aper ture 8 holds rod 24exactly in upper portion of the heating chamber.. The cone sha ed head 7forms a closed steaming tube a er rod 24 is inserted in'aperture 8. Aslightly larger diameter to aperture 8 over diameter of rod 24 allowsfor the necessary escape of the steam. The casing 1 is provided withoffset port-ions 9 and 10 on diametrically opposite sides of the casingwhich serves as entrancesfor the conductors which connect with theelectric heater enclosed by-thecasing. The shells 1 and 2 are moldedfrom insulated material which offers large resistance to heat. The lowerextremity of the shell 2 is provided with an inturned flange 11 which isshaped at 12 in such manner as to support the cylindrical heaterstructure 15.

The electric heater shown at 15 may be formed in any desired manner. Ihave illustrated the turns 14 of resistance wire embedded in afsuitablerefractory or heat-resisting material shown at 16 and forming heatingmeans between the walls of the cylindri+ cal member 15. A ring member 30is positioned interiorly of the casing 1 and provides an abutmentagainst which the upper ex tremity of the cylindrical member 15contacts. The heater structure is assembled as shown, I have shownconductors 21 and 22 passin through the entrances 9 and and lowerportion of the heater provides a guide on which the hair of the patronis wound during a hair'waving operation. The plate projecting lug 31 andshifting the member 25 has a plurality of heat-resisting projections 26thereon which connect to heat-.. resisting plate member 27 which iscovered on its lower surface by means of a pad represented at 28. Anaperture formed in pad 28 and in plates 27 and 25 permits the strands ofhair represented at 29 to be passed into the heater and locked inposition by rotative movement of the plate member 31 by rotativelymoving the plate 31 by grasping the ug with respect to the lug 25*. Inorder to prevent any dripping of condensate from the heater, I provide aplurality of absorbent gaskets 32 positioned on theplate member 31 asshown. The strands of hair are wrapped upon the central rod 24 by meansof the heat-resisting winder member shown at 33. This winder is setforth in more detail in my co-pending application SerialNo. 263,493,filed March 24, 1928, for permanent hair waving appliance. A wrap er isprovided as represented at 34 for hol ing the necessary softeningsolution for steaming and protecting the hair against excessive heat,and a clamp having a pair ofarms represented at 35 secures the wrapperin place. The clamp 35 is provided with a bridge member 36 at the upperextremity thereof through which the central rod 24 passes. This clampholds the wrapped assembly exactly in the center of the heating'tube,and also holds the lower portion of shell firmly against plate 31. Thisclamp 35 allows easy and instant withdrawal of the heating element andattached casing, from the hair without injury to the patron.

Itwill be observed that the heater is not in any sense locked to thehead, which is prohibited by law in several States. By simply liftingthe shell the entire assemblyand clamp is withdrawn from the heatingelement so that the patron may readily draw %way from the heater withoutinjury to the air.

The spring tension obtained b operation of spring 35 permits the assemby shown in Fig. 2 to be maintained in exact central position within theheater and 'held firmly against plate members 25 and 31' at bottom.

I have found the construction illustrated herein to be extremelypractical, and while I have described my invention in one of itspreferred embodiments, I desire that it be understood that modificationsmay be made and that no limitations upon my invention are'intended otherthan are imposed by the scope of the appended claims.
